Can't launch in Manjaro/KDE plasma

[noyannus]

No luck trying to run weresync.

Operating System: Manjaro Linux
KDE Plasma Version: 5.26.5
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
Kernel Version: 5.15.89-1-MANJARO (64-bit)
Graphics Platform: X11

Weresync 1.1.5-1,  installed with pamac.

Atttempts to launch via launcher results in a brief flicker, but no running weresync.

Command line throws an error:

$ weresync 
Traceback (most recent call last):

And weresync-gui asks for root password before the error:

A directory /var/log/weresync/ does not exist here (crash too early to write it?).
